why the hell would you have 8 on you at one time? Is your dps so bad that they cant aoe the first 4 down before the 2nd set come up and get anub down? If so forget anub-arak 25 hc you wont down p3 before the enrage. Trying to tank 8 adds is basically suicide. There is a high chance of a back hit which would be instant death you will take enormous damage and could easily die at any time. All in all it is a bad idea and BARELY possible if that.
